standards, including for environmental protection.Our customers' recognition for
the quality of our products and the sustainability of our company, demonstrates the
efficiency of our quality system.
CERTIFICATIONS
Certified ISO 9001 since 1994, Radiall has a
pro-active policy in terms of conforming to
international standards. Today, all Radiall sites
are certified to ISO 9001:2000 and some
dedicated activities are AS9100 or TS 16949. Our process approach gives us the
tool for continuous improvement in all our activities.
A major step in our environment policy was the ISO 14001
certification in 2001 of the Voreppe plant. Radiall complies with
European directives such as RoHS for hazardous substance
restrictions and EuP for environmentally friendly designs for energy-
using products.

Coaxial
Attenuators TECHNICAL INFORMATION
I DEFINITION
A coaxial attenuator is a linear passive bidirectional transmission line component designed to be inserted between two
coaxial lines in order to reduce the input power in a matched system by a predetermined ratio without otherwise disturbing
the behaviour of the equipment. The ratio of input to output power is expressed in logarithmic terms where
3 dB as a power ratio is 2, 6 dB is 10, 20 dB is 100 and 30 dB is 1000 etc...The power absorbed by an attenuator is returned
to the environment through heat transfer by convection or conduction cooling.
II GENERAL SPECIFICATIONS
In general, RADIALL attenuators are designed in accordance with MIL and NFC standards.
" TECHNOLOGY
RADIALL coaxial attenuators can be classified technically into 3 main types depending upon
the resistive element used.
D High frequency and low power attenuators use Tantalum Nitride thin film deposits on
Alumina substrates.
D High frequency and medium power attenuators use Tantalum Nitride thin film deposits on
Aluminium Nitride substrates.
D High power attenuators use Ruthenium Oxide thick film circuits printed on alumina
substrates sticked to a shape of Aluminium Nitride as a cooling sink.
RADIALL has decided to remove Beryllium material from its whole range of medium and high
power attenuators. Indeed, Beryllium Oxide dust is highly toxic when scribing or machining or
laser trimming. RADIALL has replaced this material by Aluminium Nitride which has excellent
heat conductive properties and is absolutely safe for the environment.
" MECHANICAL CHARACTERISTICS, MATERIALS AND FINISHES
All materials and finishes are in accordance with applicable MIL and NF specifications.
All connectors used in our attenuators are in accordance with applicable MIL, DIN, NF and CEI
specifications.
